Added a News box on the right side of the intro text, to more or less mirror the slideshow. This allows a visitor to easily see what the latest developments are, without waiting for the slideshow to scroll. It's also easier to maintain, and more accessible. I commented out the 2.4.8 image in the slideshow.

Numerous small problems, like unencoded ampersands, missing alt-text on images, etc. At least the front page pdl.perl.org now passes validation. Also incorporated a few changes that had been made to the website put never put into the git repo.
